Be it known. that I, VICTOR HJENGLAND,

a citizenof the Unite-d States, ,anda resident ofthe city and. countyvof,lDe'nver, State of Colorado, have -invented certain -newand usefulImprovements- -lin 'QSpringCompress- I ing Mechanism,` of .whichv ,thefollowingis a description, reference being-had to thefac- Thelobject ofthe--invention-is to-provide n'ieans orreadily compressing sprmgsandmaintaining the-*compression during hand l A having-.spring engagingjaws, and. means..

preferably carriedbyfone of saidy members, for' clamping the'twortogethergizn adjusted relation. l In prdervthatzanextra.:long-spring or an unusually.'.stiffispringamay belicom-'f pressedand handled, a pair of headsihavin gseats4 for thehendsof .1. theLispring, are emrlered, ,theseheade bengdapted t be placed in -avisel-oretheililefor compression oit the spring and having notches intheir edges for receiving the jaws of the extensible retaining device,whereby the compressed spring may be readily transferred from the viseand handled.

In the drawings wherein certain embodi ments of the invention aredisclosed,

Fig. 1 is a perspective view showing the extensible compressing andretaining device partially extended;

Fig. 2 is a plan thereof showing a slightly modified form of clamp;

Fig. 3 is a longitudinal section taken on the line 3 3 of Fig. 2;

Fig. 4 is a transverse section taken on line 4%-4 of Fig. 1;

Figs. 5 and 6 are tace and edge elevations respectively of the notchedspring engaging healds as indicated by lines 5-5 and 6 6; anc

Fig. 7 is an elevation indicating the manner of use of said heads.

The compressing and retaining device comprises two slidably connectedmembers 10 and 12, the member 10 having two spaced rails connected by ahead or spring engagcomp anyingdrawings,forming -a part here ing jaw 14.The member' 12 is in the form of tongueslid'aloly mounted between y.therails Q 10 andhavmg a spring enga-ging jaw 155r The slidable connectionbetween these. members is had by a tongue and-groove conf nectioncomprising beveled tongues 16 on.

in ltheluse of thisdevice, the members are extendedfa spring placedbetween the jawsv 14 and 15, pressure placed upon the jaws-' 14` and 15to compress-the spring S, and the clamping element 24 or 25 operated tobind the parts for retaining the spring in com pressed relation.

In the event that the spring S is too long for the device, or too stifffor easy compression, the same may be placed between a pair of headshaving one or more notches 82 in their edges for the purpose ofreceiving the jaws 14 and 15. These heads carry frusto-conical orsimilar bosses 34 tor seating the ends of the spring and are of suchsize as to accommodate various spring sizes. lVhen the heads 30 areplaced between the jaws V of a vise or the like, tthe bosses 34 retainthe ends of the spring during compression. The jaws 14 and 15 are thenplaced in the notches 32 and in engagement with the ends of the spring,and the clamp set. Release of the jaws V of the vise leaves thecompressed spring between the jaws 14 and 15 of the compressing andretaining device 10, 12. The friction between the edges of the rails 10and tongue 12 and the walls of the tongue and groove connection 16, 18is ample to retain the parts even under the tension of the compressedspring S, when the clamp is set.

By means of the construction herein disclosed, a spring may be readilycompressed and held in compressed condition for placing in position onthe. engine, clutch or other part. Preferably a compressing device ofthis invention will ordinarily be placed at each side ot the spring tobe retained.

I claim:

l. A spring compressor having a pair of relatively movable membersprovided with spring engaging jaws, one member having a pair of spacedside rails on which the respective jaw is nounted, and the other memberhaving a tongue slidably mounted in and between said rails, and meansfor clamping the tongue between the rails, said means projectinglaterally from one side of the device at the outer side of one of therails.

2. A spring compressor comprising a pair of members having springengaging jaws, one member having a pair of spaced rails and the othermember having a tongue slidably mounted between said rails, and aclamping device carried by one rail and engaging the other rail tocompress the same against said tongue.

3. spring compressor comprising a pair of members having spring engagingjaws, one member having spaced rails and the other member having atongue slidably mounted between said rails, a clamping device carried byone rail for engaging and compressing the other, and a stop carried bysaid tongueto engage against said clamping ldevice to prevent separationof the memers.

el. In combination, a pair of heads having seats for the ends of aspring, and a pair of slidable members having jaws, said jaws also beingadapted to engage the ends of the spring carried by said heads, saidmembers having means to lock them together to retain the spring betweenthem, said heads being separate from said members and adapted to beplaced in a vise with the spring therebetween for compression of thespring.

ln combination, a pair of heads having seats for the ends oi a springheld between them, each head having a notch in the side thereof, and apair ot slidably connected members having spring engaging jaws adaptedto be received in said notches for engagement with the ends of thespring held by said heads, and means to clamp said members together toretain the spring.

6. ln combination, a pair of heads having seats for the ends of a springheld between them, each` head having a notch in the side thereof, and aspring retainer having spring engaging jaws adapted to enter saidnotches to engage the ends of the spring.

7. A spring compressing device comprising a pair of members each ofwhich has a spring engaging jaw at one end, one member having a pair otspaced rails and the other member having a tongue slidably mountedbetween said rails, and a clamping device carried by one rail andprojecting laterally from the opposite side of the compressing devicebeyond the other rail and engaging said other rail to compress the sameagainst the tongue.

ln testimon whereof I affix my signature.
